I have a CalSpa that has a high and low setting for my pump. When the pump turns on to filter or heat, it just hums and usually doesn't start. If I press the jet button to turn it up to high, then the pump kicks on and I can turn it back down to low and it will continue to run just fine.
Bad start capacitor?? I pulled mine and it has no obvious bulges or leaks.
The tub is currently drained from the winter and I would hate to fill it and end up having to drain it again to remove the pump.
Problem started last summer/fall, so I drained it and winterized it and figured I would deal with it in the spring.
Is there a way to test the capacitor off the pump?
